305-014-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-014-556-503 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 14 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and includes a green thermoplastic housing. Rated for 5 A current, it employs a solder pin termination type for secure mounting.

Edgeboard Connectors Feature Summary

• Dual female contact configuration accommodates double-sided circuit boards
• Gold plating on copper alloy contacts provides corrosion resistance
• Green thermoplastic insulation ensures dielectric stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 3.96 mm pitch is required for high-reliability applications. The 14-position count suits moderate-density interface needs. Verify that the 5 A rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-014-556-503 variant specifically addresses dual-edge applications requiring robust gold-plated contacts and a 14-pin interface.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 3.96 mm pitch and 14-position layout. Verify mechanical dimensions and terminal types match the existing footprint.
